Abstract

La présente invention concerne des compositions fournissant des cannabinoïdes solubles dans l'eau ou dispersibles dans l'eau et des procédés pour leur production et leur administration. Ces compositions améliorent la polyvalence et l'absorption d'extraits, de dérivés et d'isolats de cannabinoïdes insolubles dans l'eau. Lorsqu'elles sont ajoutées à l'eau, ces compositions sont en mesure de former une émulsion stable et peuvent fournir une concentration en cannabinoïdes allant jusqu'à 4 mg/ml sans utiliser de chaleur, d'ultrasons, de séchage par pulvérisation ou d'extrusion à haute pression significatifs.
